1. Truss structure. Truss in truss structure refers to truss beam, which is a lattice beam structure. Truss structures are often used in long-span workshops, exhibition halls, gymnasiums, bridges and other public buildings. Trusses are usually called roof trusses because they are mainly used for building roof structures.

2. Suspended cable structure is a load-bearing structure formed by flexible cable and its edge members, which is mainly used in building engineering and bridge engineering. Cables can be made of wires with good tensile properties, such as steel wire bundles, steel wires, steel strands, chains and round steel. Suspended cable structures are widely used in bridge structures, and are suitable for long-span buildings, such as sports buildings, industrial workshops, cultural life buildings and special structures.

3. Grid structure is a spatial structure composed of multiple components connected by nodes in a certain grid form. It has the advantages of small space stress, light weight, high stiffness and good seismic performance. It can be used as the roof of stadiums, theaters, exhibition halls, waiting rooms, hangars and other buildings.

4. Reticulated shell structure: Reticulated shell is a kind of spatial bar structure similar to plane grid structure, which is a spatial frame based on bars and arranged according to shell structure, and has the properties of bar system and shell.
